How New Jersey Income Tax Works
New Jersey taxes income progressively: lower portions of income are taxed at lower rates, and higher portions at higher rates. Rates range from a low percentage on the first tier of income up to higher rates on income in the top brackets. Your total state tax is the sum across all the brackets your income spans.
What Affects Your Take-Home Pay
| Deduction | Notes |
|---|---|
| Federal income tax | Separate from state tax |
| New Jersey state income tax | Progressive brackets |
| Social Security & Medicare (FICA) | Federal payroll taxes |
| NJ state payroll programs | Such as unemployment, disability, and family leave contributions |
| Pre-tax deductions | Retirement, health insurance |
NJ-Specific Payroll Items
New Jersey withholds for several state programs beyond income tax, including unemployment insurance (UI), temporary disability insurance (TDI), and family leave insurance (FLI). These small contributions reduce take-home pay and are specific to New Jersey workers.
Note: This is an estimate. Your actual tax depends on current rates, deductions, credits, and your full financial situation.
